HKO climatological mean minimum for early May registers 23.9°C. Current prognostic charts depict persistent low-level thermal advection, sustaining elevated nocturnal temperatures. Global forecast models (GFS, ECMWF ensembles) converge on a 24-25°C diurnal low for May 5, driven by robust maritime tropical airmass influence. No cold air intrusion is indicated by present synoptic setups, bolstering the probability. 95% YES — invalid if an anomalous strong northerly monsoon surge impacts the region before May 5.
Climatological baseline for HK's May 5 low is 24.5°C. GFS model ensemble means forecast 25-27°C. Subtropical ridge dominance confirms warm advection. 95% YES — invalid if strong continental cold surge occurs.
